Subject: how to read serial number from drives connected to PERC 4e/Di

Running RHEL4, Update 3 on two machines:

dell 2850, perc 4e/di, RAID0+1, HDU=Seagate Cheetah ST3146707LC dell
1850, perc 4e/si, RAID0+1, HDU=Maxtor Atlas 10K V All drives are 146GB,
10k RPM, Ultra320 SCSI

How can I read the serial number of the SCSI drives ?
Witness that smartctl and sginfo do not work with /dev/sda or /dev/sg0
--


# smartctl -a -d scsi -T permissive /dev/sda
Device: MegaRAID LD 0 RAID1  139G Version: 521X
scsiModePageOffset: response length too short, resp_len=1 offset=4
bd_len=0
>> Terminate command early due to bad response to IEC mode page
Request Sense failed, [Input/output error]

Error Counter logging not supported

Error Events logging not supported
scsiModePageOffset: response length too short, resp_len=1 offset=4
bd_len=0 Device does not support Self Test logging

[root at identity ~]# sginfo -a /dev/sg0
